Same age. Your experience is what is commonly referred to as AGEISM. In Australia (where I am) this is illegal.
It is never too late to learn and advance yourself if you so choose. It is what you contribute rather than how long you contribute that matters in the very end.
Not sure why there is such fear of mature people bettering themselves. In many cultures, "Elders" are revered. Regardless, I plan (all things considered) to live for at least another 40 years, that's a lot of contributing to go yet!
